Description

  The present invention provides a computer with an appropriate product for ordering electrical equipment storage boards such as distribution boards, switchboards, and control boards in which a large number of electrical equipment including a main breaker and a plurality of branch breakers are incorporated in a housing. It relates to the method of selection.

  Electrical equipment storage panels such as distribution boards, switchboards, and control panels as described above are: the size and type of the chassis, the capacity of the main breaker, the function (such as the presence or absence of a leakage breaker function), the type and shape, There are thousands of types depending on the number of branches, functions, shapes, etc., and when considering additional devices such as time switches, the types are almost infinite. The manufacturer stocks typical electrical equipment storage boards as standard products, and is ready to ship according to orders.

  Since the standard product is listed in the catalog, the salesperson who received the order from the customer checks the catalog for the presence of the standard product that meets the customer's request. The price and delivery date are communicated to the customer, and the order processing and shipping arrangements are made. However, there are many types of standard products alone, and it takes considerable skill for the salesman to select an appropriate product while considering the specifications and delivery times desired by the customer.

In addition, if there is no standard product that can meet the customer's requirements, the salesperson chooses whether to reconfigure part of the standard product, combine multiple units by function unit, or create a new custom product. Needless to say, orders received by these methods are naturally more expensive than standard products and require longer delivery times. Moreover, since a lot of technical knowledge is required for such an order, it takes more skill to select an appropriate product in consideration of the specifications and delivery times desired by the customer. In addition, about the method of performing the selection of the heat radiating device of an electric equipment storage panel, calculating the heat radiation amount etc. with a computer, it describes in the patent document 1 of this applicant. However, it seems that there is no conventional literature regarding a technique for selecting a product of the electrical equipment storage board itself by a computer as in the present invention.

  The present invention solves the above-described conventional problems, and can automatically select an optimal electrical equipment storage panel that can meet customer requirements without depending on the knowledge and experience of a salesman. It was made in order to provide a product selection method using a panel computer.

In order to solve the above problems, the present invention provides a computer with an appropriate product for ordering an electrical equipment storage board in which a large number of electrical equipment including a main breaker and a plurality of branch breakers are incorporated in a housing. A method of selecting,
For each standard product model number, a standard board specification database in which the size and installation conditions of the chassis, the capacity, type, number, price, and delivery date of the installed electrical equipment are stored in the storage means of the computer. possible recombinant parts of volume recombination, the type, number, price and delivery date may be stored a recombinant component database registered in the storage means of the computer, it is further divided into the trunk portion, branching portion, each functional unit of the accessory part Store the functional unit unit database in which the capacity, type, number, price, and delivery date of the unit is registered in the storage means of the computer,
A first step in which when a customer's desired specification is input, the CPU searches a standard product that matches the desired specification by accessing the standard board specification database stored in the storage means;
A second step of outputting, to the output means, the price and delivery date read by the CPU from the standard board specification database when a standard product matching the desired specification can be searched;
When a standard product that matches the desired specification cannot be searched, the CPU extracts a mismatch point between the third step,
A fourth step in which the CPU searches for a replacement part that can eliminate the extracted inconsistency from the replacement part database stored in the storage unit;
When component reclassified can be solved discrepancies could be searched, a fifth step of outputting the output means to that effect when the CPU is output to the output means and price and delivery by recombinant thereof, could not find,
In the fifth step, when a replacement part that can eliminate the inconsistency cannot be searched, the customer's desired specification can be satisfied by the combination of the functional unit units extracted by accessing the functional unit unit database stored in the storage means by the CPU. A sixth step of determining whether or not,
When a combination of functional unit units that can satisfy the customer's desired specifications can be searched, the CPU outputs the price and delivery date based on the combination to the output means, and when it cannot be searched, outputs to the output means that it becomes a custom-made board The seventh step;
It is characterized by comprising.

According to the present invention, when a customer's desired specification is input, the CPU accesses the standard board specification database stored in the storage means to search for a standard product that matches the desired specification. Output to output means. The electricity when you can not find a standard product that matches the desired specifications, CPU accesses on top reclassified parts database to which you extracted the disagreement between the two, that by the reclassification of parts recombinant retrieved from in recombinant parts database to match the desired specifications Determine if the equipment storage panel is not available. In addition, after considering the combination of functional unit units, if any method cannot satisfy the customer's desired specifications, it will output that it is a custom-made board.

  Since these searches and judgments, as well as the output of prices and delivery times, can be automatically performed in a short time by a computer, if the contents of each database are created and maintained accurately, the knowledge and experience of each salesman It is possible to automatically select an optimal electrical equipment storage panel that can meet various customer requirements without depending on the above.

Preferred embodiments of the present invention are shown below.
FIG. 1 is a configuration diagram of hardware used in the present invention, and FIG. 2 is a flowchart showing the invention of claim 1. In FIG. 2, only the first step of inputting the customer's desired specifications to the computer may be performed by a human, but all the following steps are automatically executed by the computer according to the program.

  As described above, the product to be ordered according to the present invention is an electric equipment storage board in which a large number of electric equipment including a main breaker and a plurality of branch breakers are incorporated in a casing, and the whole is conceptually shown in FIG. In FIG. 8, 1 is a box (box), 2 is a main breaker, 3 is a branch breaker, 4 is a primary feed breaker, and 5 is an accessory device. For this reason, the customer's desired specifications can be aggregated into chassis data, master breaker data, branch breaker data, primary feed breaker data, and accessory device data in addition to the delivery date and price.

  The box data is the data regarding the size and installation conditions of the box desired by the customer and the installation conditions (whether it is outdoor, indoor, wall-embedded, etc.). This is a condition that must be observed because there is a possibility that it cannot be installed. The main breaker data, branch breaker data, and primary feed breaker data are all data relating to the number of poles, capacity, the number of breakers installed in the box, and whether or not they are earth leakage breakers. In particular, it is important that the capacity and number of branch breakers satisfy the customer's wishes accurately. If the capacity and number of branch breakers are determined, the main breaker is selected accordingly. The attached device data is data related to the type, number, shape type, etc. of attached devices such as time switches and relays other than the breaker.

  As shown in FIG. 2, when the customer's desired specifications including each of the above data are recognized by the computer, the computer first executes a first step of searching for a standard product that matches the desired specifications from the standard board specification database. To do. This standard panel specification database is a collection of data on thousands of electrical equipment storage boards that are standard products by manufacturers. As shown in Fig. 3, for each model number of standard products, This is a database that registers capacity, type, number, size and installation conditions of the chassis. The standard board specification database is stored in advance in the storage means, and the stock quantity is constantly updated from an input terminal provided in the product warehouse. In the first step, the CPU simply searches the standard board specification database to see if it matches the customer's desired specifications, and if there is a match, reads the price and delivery date from the standard board specification database. The second step of outputting to the output means is executed. The output of the second step is notified directly to the customer through a salesman or via a communication line such as the Internet, and the order is completed when agreement is reached in terms of price and delivery date. After completing the order, the computer issues a shipping instruction to the warehouse or factory.

  It is only necessary to complete the order in the first and second steps described above. However, when the standard product that matches the customer's desired specification cannot be searched from the standard board specification database, the CPU extracts a mismatch point between the two. Move on to the third step. At this time, the one closest to the customer's desired specification is selected from the standard board specification database, and the inconsistency with the selected standard product is extracted. The selection algorithm at that time is as follows. .

  As shown in FIG. 4, the CPU compares the customer's desired specification with the data of the standard product in the standard board specification database, and gives priority to the selection items. As described above, if the chassis data in the customer's desired specifications cannot be satisfied, the installation may be impossible. Therefore, the chassis data is absolute data and has the highest priority. Next, since the capacity and number of branch breakers desired by the customer are important, the branch breaker data is given priority 1. If the capacity and the number of branch breakers are determined, the main breaker corresponding to the branch breaker is selected, so the main breaker data is given priority 2. Since the primary breaker is less important than these, the priority is 3 and the accessory priority is set to 4 at the lowest.

  In the example of FIG. 4, only three data of standard products A, B, and C are shown to simplify the explanation. Of the customer's desired specifications, the chassis data is 500 x 1400 x 160 mm for the wall-embedded type, and only these standard products A, B, and C match the chassis data of the desired specifications from the standard board specification database. An explanation will be given. Next, the branch breaker data of the priority order 1 includes 40 circuit breakers having a capacity of 50 A and a shape type C according to the customer's desired specifications. The standard products A and B satisfy these requirements, but the standard product C is excluded at the priority level 1 stage because it has only 30 branch circuits.

  Next, the main breaker data of priority 2 is a leakage breaker having a shape type of A and a capacity of 250 A according to customer's desired specifications. Of the standard products A and B, since A does not have an earth leakage breaker, it is excluded at the priority level 2 and the standard product B is selected in the example of FIG. The primary feed breaker data and the accessory data of the selected standard product B are compared with the customer's desired specifications. In the customer's desired specifications, the primary feed breaker is an earth leakage breaker, but the selected standard product B's primary feed breaker is a circuit. Although it is a breaker and the customer's desired specification requires two time switches as an accessory, the standard product B extracts a mismatch point that two relays are attached.

After the completion of the third step of extracting the inconsistent points in this way, the CPU executes a fourth step of searching for a rearranged component that can eliminate the extracted inconsistent points from a rearranged component database stored in a database. Component database, as shown in FIG. 5 recombinant to group capable components each other recombinant capacity of recombinant component, is obtained by storing the type, number, price and delivery time to the storage means of the computer. In this case, since the recombination cannot be performed if the shape type and capacity of the parts are greatly different, a list of recombinable items is collected.

In the example of FIG. 5, four trunk breakers are grouped in the trunk group 1. Similarly, groups of main breakers that can be rearranged are registered as main group 2, main group 3, and the like. The parts that can be recombined are also grouped and registered for the primary feed breaker and the accessory device. In the fourth step, the CPU accesses and searches these rearranged component databases, and determines whether or not the mismatch points extracted in the third step can be eliminated by the rearranged components.

In the above example, the extracted inconsistency is that the primary feed breaker of standard product B is a circuit breaker, but the customer's desired specification is an earth leakage breaker, while standard product B has two relays attached to it. In the desired specification, there are two points that there are two time switches. However, as shown in FIG. 5, it reclassified to circuit breaker from the circuit breaker capacity and shape types are common, reclassified the relay and the time switch is possible. When the parts reclassified in this way can eliminate the discrepancies could be retrieved from in the parts database reclassifications, and price read from in recombinant parts database, output means and a delivery date by adding the number of work days reclassified to delivery in standard machine specification database The fifth step is output. The number of work days for recombination shall be registered in the standard board specification database.

The output of the fifth step is notified directly to the customer through a salesman or via a communication line such as the Internet, and the order is completed when agreement is reached in terms of price and delivery date. Thereafter, the computer issues an instruction to the warehouse or factory to start the standard product reassignment work. If it is determined in the fourth step that the inconsistent point cannot be resolved by the rearranged part, the fact is output in the fifth step and the process is terminated. This means that selection has failed in the invention of claim 1, and thereafter it is left to the salesperson.

In the present invention, a sixth step and a seventh step are further added to the first to fifth steps . This additional portion is shown in FIG. 6 and is subsequent to the portion * in FIG.

According to the present invention, when a rearranged part that can eliminate the mismatch point cannot be searched in the fifth step, the sixth step is executed to determine whether or not the mismatch point can be eliminated by the combination of the functional unit units. Here, the functional unit unit is a unit obtained by dividing the electrical equipment storage board into three functions of a main part, a branch part, and an accessory device part. The main portion includes a main breaker and a primary feed breaker, the branch portion includes a branch circuit portion, and the attached device portion includes a time switch, a relay, and the like. As shown in FIG. 7, these functional unit units are stored in advance in a storage means as a functional unit unit database. In other words, the functional unit database is registered with the capacity, type, number, price, and delivery date of the units divided for each functional unit of the main part, branch part, and accessory device part.

  In the 5th step, we examined whether the inconsistencies could be resolved by rearranging a part of the standard product, but in the 6th step, the standard product was left and the CPU accessed and registered the functional unit unit database. The functional unit units are searched, and it is determined whether or not the customer's desired specifications can be satisfied by their combination. When combining, the gutter space of each unit is calculated and an appropriate enclosure is selected. When a combination of functional unit units that can satisfy the customer's desired specifications can be searched, the seventh step of outputting the price and delivery date of the combination to the output means is executed, and an appropriate combination of functional unit units cannot be searched. When it does, it will inevitably output that it will be a custom-made board.

As described above, according to the present invention, since the steps proceed so that orders can be received at the lowest possible price, such as standard products → partial rearrangement → combination of functional unit units → custom products, the knowledge of the salesman It is possible to automatically select an optimal electrical equipment storage panel that meets the customer's requirements without depending on customer experience.
